Description

Digital signal is switched and daisy chain connection device and the system of distributing

The application requires the priority of No. 61/492,546, U.S.'s preparation patent application of submitting on June 2nd, 2011, and it is incorporated to full content in the application by reference.

Technical field

The present invention relates to the device of a whole set of system, method, and system controlling software, provide series connection a plurality of transmitters, receiver, node, extender, or duplex simultaneous two-way device becomes daisy chain form, reach switching and the distribution of digital video and audio frequency, and do not need central switch or distributor or matrix switcher.The present invention includes transmitter, receiver, node, duplexer, control device, extender, cable, software and system.

Background technology

At present the building such as company, government, educational unit or house all has network and two kinds of electronic systems such as audio-visual.Have notable difference between the two, as: network system can process information, namely multiple electronic installation is shared identical general entity by many merits data packet and is linked in asynchronous transmission; And audio-video system distributes video-audio signal, linking between each audio-visual input source and display device is to utilize the application-specific entity of synchronous transmission to link.Therefore can learn that the mode that two kinds of systems complete the message transmission that comprises image and audio frequency is very different.

Be below that four kinds of audio-video systems reach four kinds of basic functions by four kinds of assemblies:

A) interface or transmission-receiver: as shown in Figure 1, interface (transmission-receiver) is for connecting an audio-visual input source and a display device.This interface has the function that can grow Distance Transmission.

B) switch: as shown in Figure 3, switch is for connecting multiple audio-visual input source and a display device.And can from multiple audio-visual input source, select a wherein video-audio signal to be shown in this display device.

C) distributor or distribution amplifier: as shown in Figure 5, it is in order to connect an audio-visual input source to a plurality of display devices.

D) matrix switcher: as shown in Figure 7, it can connect multiple audio-visual input source and multiple display device.And can from multiple audio-visual input source, select wherein a plurality of input sources to be shown on a plurality of display devices.If need long Distance Transmission between input video-audio signal and output video-audio signal, need to set up a pair of transmission-receiver to increase the distance of transmission.If the form of input video-audio signal or output video-audio signal is the form that is different from matrix video-audio signal form, need to add a video-audio signal transducer to change the form video-audio signal of this input video-audio signal or output video-audio signal.

The traditional audio-video system that contains said modules has following restriction and disappearance:

A) centralized design makes the cable of all output and input all must be collected to single position to be connected to switching or distributor.For example: one has the meeting room at 20 seats, each position all configures one and has VGA (visual graphic array, Video Graphics Array) notebook computer of port, just have 20 VGA cables from view table across or be placed in floor and be collected to instrument stan.Thus, can increase the difficulty that audio-video system sets up and also can make visually not attractive in appearance.

B) centralized design also can make the cable of each output and input increase because need are collected to central equipment the puzzlement that the increase of length ,Ci Yi representative conference is set up.Because the main video-audio signal linking format of image output need be converted to the video-audio signal forms such as HDMI (digital high-resolution multimedia interface, High Definition Multimedia Interface), DisplayPort (digital video standard) and DiiVA (the audio-visual standard of digital bidirectional) by simulation VGA form and aberration video-audio signal.Because all types of digital audio-video signals has wider bandwidth, therefore be not suitable for, by as used long cable to transmit in current system, therefore need to setting up more expensive transmission-receiver to strengthen transmission range.

C) tradition is switched input and the output with distributing equipment with fixed number.This representative is when the number of user wish increase input and output after a period of time or increase different video-audio signal forms, as HDMI, use while expanding its audio-video system, just need remove originally old matrix and switch or distributor, and then larger equipment, the more cables of increase of installing.For receiving the video-audio signal form upgrading, and expand, be expensive thus, along with being expanded into expensive system for company's line number for video-audio signal transmission increase in demand that is representative.

D) for manufacturer and subsidiary agencies, having the input of fixed number and the equipment of output is larger challenge.It is 1 * 1 device that the device with an output and an output is referred to as; It is 6 * 1 devices that the device with six outputs and an output is referred to as; It is 1 * 10 device that the device with an output and ten outputs is referred to as; It is 16 * 8 devices that the device with 16 outputs and eight outputs is referred to as.Because too many possible application kind, manufacturer need produce hundreds of different devices just can contain all possible combination as: 1 * 1; 1 * 2; 2 * 1; 2 * 2; 4 * 1; 1 * 4; 4 * 2; 2 * 4; 4 * 4 etc.. until 512 * 512 to reach client's demand.In addition, different video-audio signal forms are as VGA, HDMI, DisplayPort, DiiVA all need the device of one group of special use, so can roll up that manufacturer and its agent need stock up and the product category of stock.In order to meet rapidly client's demand, agent must have huge stocks, and this is a very expensive stock control challenge; For manufacturer and subsidiary agencies, be also financially with logistics on problem.

E), for any one output or output, if long Distance Transmission is essential, need to increase a pair of transmission-receiver to strengthen transmission range.

F) if output is different from matrix signal form with pattern of the input, need to install video-audio signal transducer or the video signal resolution converter of a costliness.

G) centralized design liaison remote control device also must be connected with central control unit.Most switching device shifters only have a port.In meeting room or formula computer classroom, may there is plural platform computer and user, and each user all wishes to utilize single button its Computer display picture can be projected to large-screen, therefore complexity, a costliness must be installed and have and allow each user control system of controllers of use individually, be inconjunction with and contain a plurality of control cables.

H) some integrated system has basic outfit in order to expand in the future, extends to 8 * 8 as 4 * 4, and also can coordinate customized demand.Wherein, assembly has several slots and the quantity that can select input with output through mounting software.But this mode only allows limited customized.For example: if an assembly has 8 input slots and 8 output magazines, its effect that can present need be worked as when input all approaches 8 with the quantity of exporting and just be represented; But having 8 * 8 system all incurs a considerable or great expense conventionally.For user, in this system, being only equipped with 6 * 1 does not also calculate.And these all just utilize a maincenter core that possesses standard expansion slot in integrated system to be equipped with above-mentioned expansion.This just means that the restriction relevant to centralized design and defect are the problems that current needs solve.

Some network equipment uses daisy chaining to be connected to each other, but its procotol of utilizing and Multitask Data package can not be applied to the audio-visual distribution of high-quality.The video and audio product of some simulation utilizes daisy chain to connect, but the transmission of device in daisy chain and device can cause simulating video-audio signal accumulation, decays.Therefore the quantity that, analogue means can really be applied in daisy chain is therefore limited.
